i'll try to update the online manual (compiled &quot;read.thedocs&quot;) soon.

to address your progress in the tutorial, when you use that number node to scale the vertices, they are indeed scaling. If you look carefully, you see even in the image that the white-dots (vertices) are scaling outwards. In the top example.
In the bottom example, the input into the node is not correct. The node in the tutorial you are following (the old viewer node) handles the same input differently, you'll notice the old node had a socket that accepted both Edges and Faces/Polygons at the same time.  The New ViewerDrawMK3 node however has separate sockets for edges and faces and also reads the socket data differently. The node has gone red to indicate a problem with the input, it will do nothing until the input is corrected.
You will ( i am sure ) have better luck following the tutorial updated for b.28. Which i linked to above.
